**Reno Siding: Cheap Veneer Breeding Deadly Lung Mold?**

By Franklin Everett Shaw

December 31, 2025

The air in Reno, especially in older neighborhoods, can carry more than just the scent of sagebrush and pine. It can carry the invisible threat of mold, lurking behind seemingly innocuous veneer siding. Many homeowners are unknowingly living with a potential health hazard, and it’s time to shed light on this issue.

Reno’s older homes, particularly those built before stricter building codes were enforced, often feature cheap veneer siding. This siding, while initially affordable, can become a breeding ground for mold, especially Stachybotrys chartarum, the infamous “black mold.” The problem? Veneer siding, especially when poorly installed or maintained, traps moisture. This creates the perfect environment for mold to thrive, leading to serious respiratory problems and potentially impacting property values.

Let’s get real: ignoring this problem won’t make it disappear. It’s time for Reno homeowners to take proactive steps to identify risky siding, understand the health implications of mold exposure, and learn how to remediate mold growth effectively. This isn’t just about home maintenance; it’s about protecting your health and your family’s well-being.

Identifying Risky Siding: A Reno Homeowner’s Guide

The first step is identifying whether your Reno home is at risk. Here’s what to look for:

• Age of the Home: Homes built before the 1990s are more likely to have older, less moisture-resistant veneer siding. Check your property records at the Washoe County Assessor’s Office website (washoecounty.us) to determine your home’s age.
• Type of Siding: Common types of veneer siding include plywood, hardboard (Masonite), and composite materials. These are more susceptible to water damage than modern options like fiber cement or vinyl.
• Visible Damage: Look for signs of warping, cracking, bubbling, or discoloration on the siding. These are telltale signs of moisture intrusion. Pay close attention to areas around windows, doors, and where the siding meets the foundation.
• Soft Spots: Gently press on the siding in various areas. If it feels soft or spongy, it’s likely waterlogged and potentially harboring mold.
• Musty Odors: A persistent musty odor inside or outside your home, especially after rain or snow, can indicate mold growth behind the siding.
• Poor Ventilation: Overgrown landscaping or blocked gutters can contribute to moisture buildup around the siding. Ensure proper drainage and airflow.

Case Study: The Hidden Danger in Sparks, Nevada

A homeowner in Sparks, Nevada, noticed a persistent musty smell in their living room. They initially dismissed it as “old house smell.” However, after experiencing persistent respiratory issues, they hired a mold inspector. The inspection revealed extensive Stachybotrys growth behind the veneer siding, which had been installed in the 1970s. The siding had deteriorated over time, allowing moisture to penetrate and create a breeding ground for mold. The remediation process was costly, involving siding replacement and professional mold removal. This case highlights the importance of early detection and proactive maintenance.

Health Hazards of Mold Exposure: Reno’s Unique Challenges

Reno’s high desert climate, with its fluctuating temperatures and occasional heavy snowfall, can exacerbate moisture problems in veneer siding. Mold exposure can lead to a range of health issues, including:

• Respiratory Problems: Coughing, wheezing, shortness of breath, and asthma exacerbation are common symptoms.
• Allergic Reactions: Skin rashes, itchy eyes, runny nose, and sneezing can occur.
• Neurological Issues: Headaches, fatigue, memory problems, and difficulty concentrating have been linked to mold exposure.
• Immune System Suppression: Prolonged exposure can weaken the immune system, making individuals more susceptible to infections.

Stachybotrys chartarum, in particular, produces mycotoxins, which can be especially harmful. Children, the elderly, and individuals with pre-existing respiratory conditions are particularly vulnerable.

Mold Remediation: A Step-by-Step Guide for Reno Homeowners

If you suspect mold growth behind your siding, it’s crucial to take action. Here’s a step-by-step guide:

1. Professional Inspection: Hire a certified mold inspector to assess the extent of the problem. They can identify the type of mold and determine the source of moisture. Look for inspectors certified by organizations like the IICRC (Institute of Inspection, Cleaning and Restoration Certification).
2. Containment: Seal off the affected area to prevent mold spores from spreading to other parts of your home. Use plastic sheeting and duct tape to create a barrier.
3. Moisture Control: Address the source of moisture. This may involve repairing leaks, improving ventilation, or addressing drainage issues.
4. Mold Removal: For small areas (less than 10 square feet), you may be able to handle the removal yourself. Wear protective gear, including a respirator, gloves, and eye protection. Use a HEPA vacuum to remove loose mold and debris. Clean the affected surfaces with a mold-killing solution.
5. Siding Replacement: If the siding is severely damaged, it will need to be replaced. Consider upgrading to a more moisture-resistant material like fiber cement or vinyl.
6. Professional Remediation: For larger areas or if you’re uncomfortable handling mold removal yourself, hire a professional mold remediation company. They have the expertise and equipment to safely and effectively remove mold.
7. Post-Remediation Testing: After the remediation is complete, have the area tested to ensure that the mold has been successfully removed.

Common Mistakes and Pitfalls

• Ignoring the Problem: Delaying action can worsen the problem and increase the cost of remediation.
• DIY Without Proper Protection: Attempting to remove mold without proper protective gear can expose you to harmful spores.
• Using Bleach Alone: Bleach can kill surface mold, but it doesn’t penetrate porous materials to kill the roots. Use a mold-killing solution specifically designed for mold remediation.
• Failing to Address the Moisture Source: If you don’t fix the underlying moisture problem, the mold will likely return.
• Improper Disposal: Dispose of contaminated materials properly to prevent the spread of mold spores.

Reno Regulations and Mold Disclosure

Nevada law requires sellers to disclose any known material defects in a property, including mold. However, the specific requirements for mold disclosure can be complex. Consult with a real estate attorney to ensure compliance with all applicable regulations. The City of Reno also has building codes that address moisture control and ventilation. Familiarize yourself with these codes to ensure that your home is up to standard.

Actionable Insights for Reno Homeowners

• Schedule a Siding Inspection: Have your siding inspected by a qualified professional, especially if your home is older or you suspect moisture problems.
• Improve Ventilation: Ensure proper ventilation in crawl spaces and attics to prevent moisture buildup.
• Maintain Gutters and Downspouts: Keep gutters and downspouts clean and free of debris to ensure proper drainage.
• Trim Landscaping: Trim bushes and trees away from the siding to improve airflow.
• Consider Upgrading Siding: If your siding is old or damaged, consider upgrading to a more moisture-resistant material.
• Document Everything: Keep detailed records of inspections, repairs, and remediation efforts.

Don’t let mold silently compromise your health and home in Reno. By taking proactive steps to identify risky siding, understand the health implications, and remediate mold growth effectively, you can protect your family and your investment. It’s time to breathe easier in the Biggest Little City.
